I think you need some re-design because this is neither neat graphics, nor something about 8-bit stuff. Go check some late 80s games to see how they do. Assuming the gameplay is great and addictive, you only have to do some revamped old-style art and you're done. I find this excellent and I guess it will become more or less popular game at kon.
It is more of pan, no tilt. Whatever, nice one. And tough sometimes. BTW, I wonder if it utilizes my NVIDIA thingy for acceleration? And strangely enough I can't go full-screen.
